318 Background: To improve poor therapeutic outcome of current practice of chemoradiotherapy (CRT), high dose helical tomotherapy (HT) with concurrent full-dose chemotherapy has been performed on patients with locally advanced pancreatic cancer (LAPC), and the results were analyzed. Methods: We retrospectively reviewed 39 patients with LAPC treated with radiotherapy using HT (median, 58.4 Gy; range, 50.8-59.9 Gy) and concomitant chemotherapy between May 2006 and May 2009. Radiotherapy was directed to the primary tumor with a 0.5 cm margin without prophylactic nodal coverage. Twenty nine patients (79%) received full-dose (1000 mg/m 2 ) gemcitabine based chemotherapy during HT. After completion of CRT, maintenance chemotherapy was administered to 37 patients (95%). Results: The median follow-up was 15.5 months (range 3.4-43.9) for the entire cohort, and 22.5 months (range 12.0-43.9) for surviving patients. The 1- and 2-year local progression-free survival rates were 82.1% and 77.3%, respectively. Eight patients (20%) were converted to resectable status, including one with a pathologic complete response. The median overall survival and progression-free survival were 21.2 and 14.0 months, respectively. Acute toxicities were acceptable with no gastrointestinal (GI) toxicity higher than grade 3. Severe late GI toxicity (≥ Grade 3) occurred in 10 patients (26%); one treatment related death due to GI bleeding was observed. Conclusions: High-dose helical tomotherapy with concurrent full-dose chemotherapy resulted in improved local control and long-term survival in patients with LAPC. Future studies are needed to widen the therapeutic window by minimizing late GI toxicity.
